After Revere sold the house in 1800, it soon became a sailor's boarding house. By the second half of the nineteenth century it was an immigrant tenement, and the ground floor had been remodeled for shops. At various times the building held a candy store, a cigar factory, an Italian bank, and a vegetable and fruit business. A place we now treat as a shrine spent much of its life as an ordinary, crowded, working building. Then came the rescue. In 1902, Paul Revere's great-grandson, John P. Reynolds Junior, bought the building to make sure it would not be demolished. Pauline Revere Thayer, a great-granddaughter of Revere and a cousin of Reynolds, was also a key figure in the early years of the Paul Revere Memorial Association and in the restoration of the house. In April 1908, the house opened to the public as one of the earliest historic house museums in the nation. More recently, archeologists have worked at the house too. Excavations carried out between 2011 and 2013 added to what we know about the site.
